Abstract (en)
[origin: EP2413556A1] A method and an apparatus for handling data sending and receiving are disclosed by the present invention, where the method for handling data sending includes: allocating the number of space transmission layers and pilot frequency resource for transmission at each transmission layer (101); generating pilot frequency resource information according to the number of space transmission layers and the pilot frequency resource for transmission at each transmission layer (102); and sending the pilot frequency resource information to a UE (103). The embodiments of the present invention can enable the UE to determine the specifically used pilot frequency resources to effectively distinguish the specific user channels, obtain correct channel estimation values, improve the channel estimation performance, and obtain correct service data.
